Patented July 31, 1934 UNITED STATES PATENT OFFICE 4 Claims.

The invention relates to bottle stoppers of the type which when insertedin a bottle will make this non-refillable, and is a further improvementon the device shown'in my application for Letters' Patent, filedNovember 25, 1932, bearing Serial No. 644,172. It has for its mainobject to provide a bottle stopper which can. not be removed from thebottle when once inserted, and which positively prevents theintroduction of any liquid or other substance into the bottle.

Another object is to provide a bottle stopper which may be adapted tomake any type of bottle non-refillable without having to alter its shapeor change its general appearance. .A further object is to provide abottle stopper, of simple and inexpensive construction, which can beinserted in a bottle as readily, and with practically the sanzle means,as the ordinary cork now generally use These and various other objectsand advantages will be readily understood from the following descriptionand from the accompanying drawing of a preferred embodiment of theinvention in which, however, modifications may be made without departingfrom the scope of the appended claims. In the drawing Fig. 1 is afragmental and cross-sectional view of a-bottle with a stopper showninserted therein; the view is taken on line 1--1, in Fig. 3;

Fig. 2 is a similar view showing the bottle tilted and the valves in thestopper in the open positions;

Fig. 3 is a. top viewoi Fig. 1;

Fig. 4 is a sectional top view taken on line in F Fig. 5 is a sideelevation up the stopper; and

Fig. 6 is a modification of the valves.

Referring now to all the views, simultaneously, the stopper comprises abody member preferably formed of two semi-circular halves 10 and 11 oneach of which a half flange 12 is provided so that, when the two partsare assembled, a continuous flange is formed around the body member. Achamber 13 is formed in the stopper above flange 12, while anotherchamber 14 is formed in the lower end of the stopper. A concentricopening 15 leads from the upper chamber to the lower chamber and in thisa valve stem 16 is free to slide.

The upper end of the valve stem is provided with a valve disk 1'? whichis formed integrally with the stem, while the valve 18 is preferablyslidingly mounted on the lower end of the valve stem and adapted toclose an opening 19 which of the two partsmakln leads into the chamber14. A plurality of radical grooves 20 are formed in the inner part ofthe body members and extend from the chamber 13'to the chamber 14 so asto form longitudinal passages through the body member. The valve disk 17is of.v suiiicient diameter to close these passages. The body memberparts are held together and secured tightly in the neck of the bottle 21by a tubular member 22 made of resilient material, such as cork. Thebottleis made with an annular recess 22 A against the bottom of whichthe flange 12 seats. The recess in the neck of the bottle may be made ofsufiicient depth to make it possible to insert an ordinary cork in,addition to the stopper. When the bottle is in its upright and normalposition, the valves 17 and 18 close, the upper ends of the grooves 20and the opening 19, respectively. The valves will remain in thisposition until, the bottle is tilted to the approximate position shownin Fig. 2. whereupon the valve stem, and consequently the valves, willslide so as to uncover the grooves 20-as well as the opening 19. Thecontents of the body will now flow freely through the opening 19,chamber 14, some of the passages 20, chamber 13 and through a pluralityof openings 23 which leads from the chamber 13. While the liquid isflowing from the bottle, air is admitted to it through one or more ofthe openings 23 and through one or more of the passages 20. The movementof the valve disk 1'7 is limited by the top 24 of the chamber 13. An airvent 25 is preferably formed in this top and a plurality of smallprotrusions 26 are preferably formed on the upper faceof the valve disk17 so as to prevent it from contacting directly with the top 24 and thusprevent the escape of air through the hole 25. As the flange 12is seatedagainst the bottom of the recess 22, it is obviously impossible to pushthe stopper into the-bottle. Furthermore, this flange prevents the corkmember from being destroyed or removed either by mechanical or chemicalmeans. The chamber formed around the upper valve makes it impossible tohold this valve open so as to thereby refill the bottle. Furthermore,even if this valve should for some reason stick or otherwise stay open,the lower, sliding valve 18 would close the opening 19 and prevent anyliquid from being introduced into the bottle. In the modification shownin Fig. 6 the lower valve 18 does not slide on the valve stem 16 but ismoulded integrally with it. In some instances this construction ispreferable. In other instances one or the other of the valves may beomitted. In case the upper housing is omitted and when the lower. valveis slidingly mounted on the valve stem, a detent 27 is formed on thevalve stem to retain it in place when the bottle is tilted.

The present construction makes it easy to insert the stopper in a bottleand removes all danger of breakage; in that, a tubular tool may be usedwhich engages directly on the flange and thus remove any danger ofcrushing the chamber 13 even when considerable pressure is needed forinserting the stopper.

It is evident that many modifications may be made in the device shownwithout departing from the scope of the appended claims and it isthere-- fore to be understood that the illustration and description isprimarily to show a preferred form. of the device which is simple andinexpensive in its construction and effective in its operation.

Having described my invention and its objects, what I claim as new. andwish to protect by Let ters Patent, is':

1. A bottle stopper for preventing the refilling of a bottle; comprisinga body member insertable in the neck of a bottle; a plurality ofpassages formed longitudinally through said body member; a concentricopening formed in said body member; a valve stem, having a valve disk atits upper end of suflicient size to close all said passages, slidinglymounted in said opening; a chamber formed in the lower part of the bodymember; an orifice leading from the bottom of the body member to saidchamber; a valve, slidingly mounted on the valve stem, for closing saidorifice; and a housing, having a plurality of openings, formed on theupper part of the body member and in which said valve disk is contained.

2. A bottle stopper for preventing the refilling of a bottle; comprisinga body member having an annular flange insertable in a recess in theupper part of the neck of a bottle; a plurality of passages formedlongitudinally through said body member; a concentric opening formed insaid body member; a valve stem, having a valve disk at its upper end ofsufiicient size to close all said passages, slidingly mounted in saidopening, a chamberformed in the lower part of' the body member; anorifice leading from the bottom of the body member to said chamber; avalve slidingly mounted on the valve stem, for closing mid orifice; ahousing, having a plurality of openings, formed on the upper part of thebody member and in which said valve disk is contained; and a resilientsleeve secured on the outside of the body member, below said flange, forsecuring the stopper in the neck of the bottle; the said hous ing beingof smaller size than the recess in the neck of the bottle so as to allowa hollow tube to be engaged against the said flange in the insertion ofthe stopper in the bottle.
